A coupling device including a drive member that is rotatable about an axis, a driven member that is substantially aligned with the drive member and is selectively rotatable about the axis, a speed sensing member that is coupled to the drive member and is movable between a first position and a second position in response to the rotational speed of the drive member, and a clutch member that is movable between a disengaged position and an engaged position in response to movement of the speed sensing member between the first position and the second position. At least a portion of the clutch member is removable without changing the alignment between the drive member and the driven member. |
