    摘要: A limited free-motion coupling device 10 coupling an impeller 14 to a shaft 16 of a rotor 12, the coupling device 10 comprising first and second parts 20, 22 which are axially engaged for relative angular displacement about a rotational axis A, and two spherical coupling members 24 for engaging the first and second parts 20, 22 to prevent the relative angular displacement. One of the first and second parts 20, 22 is provided on the shaft 16 of the rotor 12, and the other is provided on the impeller 14. The first part 20 comprises two spaced coupling member arms 30 which project radially. The second part 22 comprises a cylindrical wall 66 extending coaxially with the rotational axis A of the coupling device 10. Two spaced arcuate channels 50 are formed in the cylindrical wall 66. Each coupling member 24 is received in and projects radially from a respective arcuate channel 50, and is freely movable between end walls of the arcuate channel 50. As the first part 20, rotates relative to the second part 22, the coupling member arms 30 of the first part 20 engage and move the coupling members 24 along the respective arcuate channels 50 until the coupling members 24 abut the end walls of the arcuate channels 50, thus locking the first part 20 relative to the second part 22.
