Abstract
A coupling device for the transmission of torque. The coupling device includes a drivable rotor part, an output shaft rotatably connected with an armature part, a hysteresis part disposed on the armature part, permanent magnets configured to generate a magnetic field through which magnetic field a torque can be transmitted from the rotor part to the armature part, a stator part in which an electromagnet is disposed, the electromagnet being configured to induce a magnetic flux in the rotor part so as to adjust a torque from the rotor part to the armature part, and a synchronous coupling disposed between the stator part and the armature part.
