The coupling finds application in agricultural machines.
Relative angular position between two shafts can be adjusted to make
the machines compact when not working (the coupling is folded up and
the shafts are not aligned). The fingers are kept always in contact to
maintain proper alignment, when the coupling is folded down.
Note: rotary axes of the shafts and rotary axis of the movable bearing are not concurrent.
The transmission is possible even when the shafts are not aligned
