A car door-shaft door coupling for arrangement on a door wing with a door leaf plane includes a pivoting lever, which is rotatably mounted on a rotational axis on a support element, and a moveable element, which is coupled to the pivoting lever in such a manner that a movement of the moveable element carried out parallel to the door leaf plane causes the pivoting lever to perform a rotational movement for coupling a car door to a shaft door and change the distance between the lever and the door leaf plane by horizontal movement.
