Valve assemblies are described that provide magnetic coupling between a valve actuator and a valve body housing the valve rotor and stator. A valve assembly embodiment, includes, but is not limited to, a valve body, the valve body including at least one magnet, and a rotor and a stator configured to define a plurality of fluid flow passageways; a valve actuator configured to drive the rotor via a drive shaft; and an actuator mount coupled to the valve actuator and configured to magnetically couple with the at least one magnet of the valve body to magnetically couple the valve body and the valve actuator.
