A fault-tolerant electromechanical actuating device for converting an electrical actuating signal into a mechanical output actuating value for use in vehicles, having two mutually independent control loops. Each loop has at least one controller and at least one electric motor which is driven by this controller and which, in each case via a self-locking transmission, drives the input to a summing transmission, which superimposes the actuating values of the actuating motors to form the output actuating value. The fault tolerance or reliability of the actuating device is ensured by a comparator controller, which monitors the functions of the other controllers. Interfaces between the controllers and between the subsystems ensure stringent isolation of electrical potential.
