  • Patent number: 11131370
    Abstract: A controlling device may include an actuator for mechanically actuating a component. The actuator may be driven by an electric motor. The controlling device provides a return spring. In the case of a failure of the electric motor, the return spring brings about a shifting of the actuator into a starting position. The return spring may be mounted in the controlling device so that it prestresses the actuator into the starting position with a predetermined minimum restoring force.
