A differential adjuster that utilizes a tool interface for affecting either a coarse adjustment or a fine adjustment is presented. The differential adjuster includes an intermediate actuator sleeve with a tool interface to accommodate a tool for performing adjustments. The intermediate actuator sleeve includes a first threaded surface operatively engaging a housing to adjust the position of the intermediate actuator sleeve relative to the housing, and a second threaded surface operatively engaging a push rod to adjust the position of the intermediate actuator sleeve relative to the push rod. The first threaded surface contains threads that are a different pitch than the second threaded surface.
