3. The adjustable (vernier) coupling, which
provides a means of finely adjusting the relationship of
two interconnected rotating shafts (fig. 11-19).
Loosening a clamping bolt and turning an adjusting
worm allows one shaft to rotate while the other remains
stationary. After attaining the proper relationship, you
retighten the clamping bolt to lock the shafts together
again.

each splined to its respective shaft, are bolted to the
metal disk. The flexible coupling provides a small
amount of flexibility to allow for a slight axial
misalignment of the shafts.
4. The adjustable flexible (vernier) coupling (fig.
11-20), which is a combination of the flexible disk
coupling and the adjustable (vernier) coupling.
UNIVERSAL JOINT
To couple two shafts in different planes, you need
to use a universal joint. Universal joints have various
