Abstract
The invention relates to a multi-groove and spline connection between a gear and cardan shaft of a rotary piston machine with an internal axis, wherein external toothing at the head of the cardan shaft engages internal toothing of the gear and an axial abutment co-operates with the end face of the head. The abutment is such that it is only contactable by the teeth of the head of the cardan shaft.
