The Earth raised tides on the Moon. This caused the Moon's rotation to
slow down and eventually stop relatrive to its orbit.
There are many other instances.

Much more interesting is where rotation and orbital motion are in
multiples.

The presence of resonance is particularly interesting. It indicates
that a complete lock may not be the most stable state. There are
implications in other fields of Physics.
