Coupling device comprises two coupling elements (14, 14a) having facing front surfaces (82, 82a) moving against each other. Each coupling element has a hollow space (42, 42a) which opens into an opening (83, 83a) in the front surface and is coupled with the hollow space of the other coupling element for the transfer of fluid pressure. A piston (35, 35a) is guided in an axial direction in each of the hollow spaces. In the sealing position each piston is arranged approximately flush with or below the front surface. |
