Movement transmission device and method

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 take-off causes movement of the coupling elements, wherein movement of the coupling elements is not suitable for transmitting movement of the take-off to the drive, and wherein in the decoupled state rotational movement of the take-off causes the coupling elements to move radially and orthogonally with regard to said rotational movement of the take-off, and
• (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 take-off causes rotational movement of the coupling elements in a same direction together with the drive, 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.
