A combination magnetic particle clutch and brake device comprising a rotatable output shaft having a single magnetic coupling member mounted thereon for rotation therewith, the coupling member comprising a hollow cylindrical portion having an axis of rotation substantially coincidental with, the axis of rotation of the shaft and an annular portion extending substantially radially of the cylindrical portion. The brake section of the device includes a stationary magnetic armature and one of the portions of the member, while the clutch section includes a rotor and a stator and the other of the portions of the member. Means connect the stationary armature and the stator as a unit. Driving coils are provided for establishing magnetic flux paths through the armature and one portion of the coupling member and through the rotor and stator and the other portion of the coupling member. The armature and the rotor are spaced from and surround the coupling member so as to define a single continuous space which is filled with magnetic particles. Sealing means are provided for substantially preventing magnetic particles from escaping from the space.
