A coupling including a first coupling element having interlocking claws extending outwardly in radial direction and additional interlocking claws outwardly offset from the interlocking claws in radial direction and including a second coupling element having claws outwardly offset from the locking claws in radial direction. The interlocking claws grip behind the locking claws like a bayonet catch and the additional interlocking claws grip behind the additional locking claws like a bayonet catch while the second coupling element is rotated relative to the first coupling element. The advantage of this coupling is to absorb tensile and pressure forces as well as bending moments.

[ What is claimed is:] [1.]1. A coupling assembly adapted to connect an additional device to a vehicle, said coupling assembly comprising:a first coupling element, on which at least two interlocking claws are disposed extending outwardly in radial direction, anda second coupling element, on which at least two locking claws are disposed extending inwardly in radial direction,wherein the interlocking claws and the locking claws are so arranged and dimensioned that the interlocking claws grip behind the locking claws like a bayonet catch, when the second coupling element is rotated relative to the first coupling element, whereinat least two additional interlocking claws are additionally disposed on the first coupling element, which are outwardly offset from the interlocking claws in radial direction, andwherein at least two additional locking claws are additionally disposed on the second coupling element, which are outwardly offset from the locking claws in radial direction,wherein the additional interlocking claws and the additional locking claws are so arranged and dimensioned that the additional interlocking claws grip behind the additional locking claws like a bayonet catch, when the second coupling element is rotated relative to the first coupling element, in particular for absorbing lateral powers,wherein the first coupling element includes a base plate adapted to be attached to the vehicle and the second coupling element includes an instrument plate adapted to be attached to the additional device,wherein the base plate includes a through bore arranged centrically to the inner ring, which through bore opens conically in the direction of the outer surface of the base plate,wherein a valve is arranged on a surface of the base plate opposite the outer surface, the valve including a spring biased valve piston which extends in the direction of the through bore, wherein the valve piston controls the flow rate of a working medium being supplied to the additional device, andwherein a control pin is fastened to the instrument plate centrically to the outer ring, which enters into the through bore and displaces the spring biased valve piston in axial direction for adjusting a specified flow rate of the working medium.
