Autocoupleur with balls
- Very high degree of accuracy of release
- For extreme requests
- If the limiting moment is reached, autocoupleur cliquète and passes successively by phases of couplings and uncouplings.
- it réaccouple automatically.

Synchronous Autocoupleur or assynchrone without angular play with balls
- Very high degree of accuracy of release
- No play in the two directions of rotation
- Simple Fixing, with the integrated expansible assembler
- If the limiting moment is reached, it disconnects the kinematics of the energy source without relative movement, angular play, angle of torsion.
- Resumption of synchronism to 360°
