propeller shaft

[Philippe VIARD]

Hello everybody,
On the site Ilcats.ru like the site Neimoller, I remark on the front section of the propeller shaft four items number 36,37,38 cf the picture.
in the various discussions to achieve a change of the flector these parts are not mentioned.
What is their role?

Those are the pieces that go inside the centering cross, which is #32 in the diagram.

Cheers,

Thank you for your answer
but what is the role of these 4 pieces that are held in place compressed by a spring in piece 32?
The piece 32 is inserted into a short axle that comes out of the gearbox.
Role avoid vibrations? optimized fit on this short shaft?
