If you look at the worm gear end that fits on the coupler, you will see hole in it. Push the motor axle into it and it will be straight. When the compound dries, you can ease the shaft out a bit and it will be in a straight line.

And this stuff lasts a long time. I've used this since the early 2000's as well and never had to replace one. I've used the silicone insulation approach as well, its very low friction material good for this application with plastic on plastic movement. It works too but is more tedious. The gasket compound is easier to use and drastically reduces problems with friction and heat (heck, the stuff is used to make gaskets in automobile engines). The only negative with the gasket compound is that it has to dry overnight to solidify.

All the Best,
