The invention relates to an actuating drive (10) for a valve (11), having an activation means (17), an actuator (16) which moves the activation means (17) between two end positions on the basis of controlled or manipulated variables, and a manually activatable switching means which can be used to move the activation means (17) into at least one of the two end positions independently of the controlled or manipulated variables. In order to be able to switch the actuating drive (10) into one of the end positions thereof in a simple and convenient manner, the actuating drive (10) according to theinvention is characterized in that the switching means is an eccentric (29) which can be activated via a manual activation element (23). The invention also relates to an arrangement having such an actuating drive (10). 本发明涉及一种用于阀(11)的调节驱动器(10)，其具有致动装置(17)、调节构件(16)和可手动致动的切换装置，所述调节构件(16)使所述致动装置(17)根据控制或调节变量在两个端部位置之间移动，使用所述可手动致动的切换装置可使所述致动装置(17)独立于所述控制或调节变量而移动到所述两个端部位置中的至少一个处。为了能够以简单且方便的方式将所述调节驱动器(10)切换到其端部位置中的一个处，根据本发明的调节驱动
