• an actuating element rotatable relative to the stationary structure;
• an electric power source;
• a spindle arranged to be rotated by rotation of the actuating element;
• a locking member movable between a locked position and an unlocked position;
• an electromechanical transfer device arranged in the spindle, the electromechanical transfer device being configured to adopt a locked state, in which the locking member cannot be moved from the locked position to the unlocked position by rotation of the actuating element, and an unlocked state in which the locking member can be moved from the locked position to the unlocked position by rotation of the actuating element;
• a receiver device fixed with respect to the spindle, the receiver device being electrically connected to the electromechanical transfer device;
• and
