The present invention relates to a rotary drive for at least one leaf/casement, in particular a door leaf or a window casement, comprising: at least one output shaft (330) for coupling to the at least one leaf/casement; at least one motor (20), which acts on the output shaft (330) via at least one downstream gear mechanism (30); an energy-store module (112), which has a linear line of action and uses transmission elements (14, 32, 326) to subject the circumference of an eccentric cam disc (331), arranged in a rotationally fixed manner on the output shaft (330), to pressure; and an intermediate shaft (320), which is offset in relation to the line of action of the energy-store module (112) and is provided between the motor (20) and output shaft (330). The rotary drive is characterized in that the transmission elements (14, 32, 326) comprise a roller lever (32), which is mounted in a rotatable manner on the intermediate shaft (320) and has a cam-follower roller (326) spaced apart from the intermediate shaft (320), wherein the cam-follower roller (326), pressed circumferentially against the eccentric cam disc (331), interacts with the output shaft (330), and the energy-store module (112) is arranged on the motor side in relation to the intermediate shaft (320). The present invention also relates to a clamping piece for connection to the output shaft (330), wherein the clamping piece has a lateral lever which interacts with an eccentrically mounted and steplessly adjustable stop element. La presente invención se relaciona con un accionamiento rotativo (100) comprendiendo: un árbol de accionamiento (330); un motor (20) que actúa sobre el árbol de accionamiento (330) vía un engranaje (30) conectado posteriormente; un módulo acumulador e energía teniendo una línea de acción lineal y teniendo elementos de transmisión (32, 326) para aplicar presión en la periferia de un disco de leva (331) excéntrico dispuesto en el árbol de accionamiento (330) para la rotación junto con éste; y un árbol intermedio (320) desplazado respecto a la línea de acción referida y provisto entre el motor (20) y el árbol de accionamiento (330) . Los elementos de transmisión (32, 326) comprenden una palanca de rodillo (32) teniendo un seguidor de levas (326) separado por una distancia del árbol intermedio (320), siendo que el seguidor de levas (326) interactúa con el árbol de accionamiento (330) al estar empujado con presión en la periferia del disco de leva (331) excéntrico. El módulo acumulador de energía se dispone en el lado motor respecto al árbol intermedio (320).
