Abstract
A hydraulic machine with an orbiting displacement element connected unrotatably with an output shaft via an intermediary shaft, the intermediary shaft having at least at one end an external toothing, which engages an internal toothing, which permits a swivel motion of the intermediary shaft. The external toothing has teeth with concavely shaped tooth sides having a smaller curvature at the axial ends than in the area of the axial center.
