A coupling has face gears for transmitting torque or transverse forces between a first part provided with a first face gear and a second part provided with a second face gear complementary to the first face gear. At least one of the parts is a shaft, an axle, a pin or a flange, and it is possible to bring the first face gear into form-fitting engagement with the second face gear. At least one of the face gears has at least one groove having a constant width and a longitudinal centerline forming a semicircular arc having a respective first center of curvature in at least one section of the groove and, in at least one other section of the groove, forming another semicircular arc having a respective second center of curvature. |
