Abstract
A method of attaching a stepper motor to a throttle shaft provides constant torque transmission by connecting the shafts coaxially with a coupling that accommodates limited shaft misalignment and movement. In the preferred embodiment, the coupling comprises a fork, parallel to, and attached to, one shaft that receives a pin, perpendicular to, and attached to, the second shaft. The coupling permits the coaxial attachment of the shaft without the necessity of maintaining precise mounting tolerances.
