2116844 9303342 PCTABS00019 An absorption dynamometer includes a rotor (12) and restrained stator means (14), and in use of which the rotor energy is substantially dissipated as heat in the stator means. A cooling arrangement (16) for the stator means comprises passage means (62, 63) for coolant fluid. This passage means extends, at least in part spirally, from a fluid intake port (70) at or adjacent a first end of the stator means to an oultet port (71) at or adjacent a second end of the stator means. Also disclosed is a vibration absorption means (25) and flexible coupler means (84, 85) to dampen the vibrations of a power tool being tested.
