ABSTRACT:
A method and structure for securing a lever to a shaft of a rotary actuator in a manner which facilitates small angular adjustments between the lever and shaft is disclosed. The lever is clamped onto a segment of the shaft which is formed with a helical knurl. The lever may be slightly repositioned along the shaft to facilitate angular adjustments smaller than the angle between adjacent ridges of the knurl where the ridges have caused corresponding indentations in the lever.
