Abstract: A pressure medium operated actuator with a position regulator for regulated action on the opening and closing actuation of, for example, a process valve, and with a transmission device for transmitting the movement of a driving member to the position regulator. In order, in a position regulator of this type, to utilize a material pairing which is advantageous per se and, at the same time, to achieve movement transmission which is free of play even in the long term, the position regulator is provided with a resetting lever having a polygonal rotary slide which is prestressed in the manner of a torsion spring and which, by tilting slightly under a torsion spring effect, engages between two parallel round-rod portions of a driver connected to the push-rod.
