Patent ID: 8539802

Claim:
A device for transmitting a movement as well as corresponding forces and/or moments, the device comprising: a drive, a take-off and two coupling elements, wherein the drive and the take-off are coupled by the coupling elements in such a manner that; (i) in a decoupled state a rotational movement of the drive causes movement of the coupling elements, wherein movement of the coupling elements is not suitable for transmitting movement from the drive to the take-off, and wherein in the decoupled state rotational movement of the drive causes the coupling elements to move radially and orthogonally with regard to said rotational movement of the drive, (ii) wherein in the coupled state a moveable coupling locking element is located between the coupling elements so that the coupling elements can no longer move radially such that rotational movement of the drive causes rotational movement of the coupling elements in a same direction together with the take-off, further comprising an actuator for positioning the coupling locking element, wherein the actuator is bistable, wherein a mechanical potential formed by a storage device, has to be overcome for moving the coupling locking element from the decoupled state in a coupled state and/or from the coupled state in the decoupled state.
