This mechanism for transmitting a torque to a hydrostatic coupling of the barrel-cylinder type is characterized in that each piston of the barrel-type cylinder block is hollow and incorporates a delivery valve and that its cylinder is supplied with pressure fluid through a non-return valve; furthermore, the inner cavity of each piston is constantly connected to a chamber formed in the cylinder block and centered to the axis of rotation of this block. A valve member is movable under the control of the fluid contained in said chamber against the force of a central piston having one side responsive to an adjustment pressure. A forced-feed pressure is exerted through said non-return valve for constantly pressing the cylinder-block pistons against the corresponding swash plate.
