A dynamometer including a housing comprised of first and second parts relatively rotatable about an axis and defining a chamber, at least one brake element within the chamber carried by each part, the brake elements being in adjacency and relatively movable within the chamber, a motor and spring for moving the elements to frictionally engage and disengage the same, coolant inlet and outlet ports to the chamber, and a base mounting the housing for rotation about the axis, a transducer connected to one of the housing parts and the base, and a coupling device connected to the other of the parts and including a chuck for driven engagement with a mechanical power source, the coupling being axially extendable and allowing limited play in the radial direction.
