Simple answer, yes! Either way works. It will depend on your system's design. It could be directly in line, or parallel to the shaft. Belt linkages work as well as chain. The are things to consider with either approach. Putting too much tension on the encoder's shaft could be a problem and damage it. Not enough tension could cause slop and produce inaccurate measurements.

Sorry I don't have an actual picture, but with a bit of imagination you can see where a piece of surgical tubing stretched over both shafts here would make a fairly decent coupling. It would allow for a small amount of misalignment between the shafts as well.


The encoder in this picture has ball bearing shaft supports and practically zero rotational friction.
