There are several varieties on FIRST Choice this year - oh, it just closed a couple of hours ago. For 1/4" to 1/4" solutions, see FC17-122, or a combination of two FC17-110s with an FC17-124 between them.

Note that to couple two 1/4" shafts with tubing, you would need tubing with a 1/4" inside diameter, not outside. I have never done this, but it seems that you would want to keep the length short if your application is sensitive to sensor backlash.

I heard secondhand (no details) about a team who used a 1/4" drive socket universal joint in a coupler to isolate a potentiometer from shock loads. Yep, sounded kludgy to me too.
