A hydrostatic coupling assembly for use in the driveline of a motor vehicle includes a first coupling part ( 3 ) and a second coupling part ( 4 ); a displacement machine ( 22 ) having a first rotor ( 23 ) which is eccentrically supported relative to one of the coupling parts ( 3, 4 ), and a second rotor ( 25 ) which is connected to the other one of the two coupling parts ( 3, 4 ). The first rotor ( 23 ) and second rotor ( 25 ) form displacement chambers ( 31 ) for hydraulic fluid thereby creating a pump. An annular chamber ( 50 ) communicates with the displacement chambers through first and second connecting channels ( 34, 35 ). A sliding sleeve ( 38 ) is axially displaceable between an open and closed position in which the outlets of the first and second connecting channels ( 34, 35 ) in the annular chamber ( 50 ) are open or closed, respectively.
