"Selsyn" is a trademark for (I think it is) Superior Electric, which
used it on lots of different types of servo motors. But "selsyn" is most
commonly used to mean small wound-rotor 2-phase or 3-phase AC servo
motors. When two such motors are set up right, they behave exactly as if
there is an invisible shaft connecting them. Any movement on one shaft
is exactly copied by the other shaft; stopped at any angle, or rotating
at any speed, forward or backward.
