Abstract
The invention relates to an actuator device for torque transmission equipment such as a clutch, e.g. a friction clutch or dog clutch, or a brake, comprising at least two electric motors, wherein the rotors of the electric motors are kinematically coupled together via a summation gear, and the summation gear has an output side which is coupled to an actuator of the torque transmission equipment in such a way that a state of the actuator can be set as a function of a relative rotation between the two rotors.
