Hi Adnandogar

You have a shaft coupled to an instrument / element.

I would think the shaft is used to transfer info to the instrument.

In other words an elementary data shaft.

Abnandogar, I believe that your english translator is not working very well...

However I think I sorted it out..

Shaft alignment is accomplished with either dial indicators, or a laser alignment kit. Here are some links to both...
