This patent describes an apparatus for controlling the throttle of a fuel burning engine from either a shaft powered by automatic fuel control equipment or by the translational motion of a manually positioned throttle lever. The apparatus is attached to the engine via a throttle shaft extending outwardly from the wall of the engine fuel-air metering system, the apparatus comprising: an outer housing shell having a generally cylindrical interior and a lever arm rigidly attached to and extending radially away from the periphery thereof, the lever end furthest from the periphery of the outer housing shell being pivotally connected to the manual throttle lever; an output spool mounted for rotation within one end of the outer housing shell, the output spool having an axial boring at its outermost end sized to receive and be secured to the throttle shaft. The inward facing end of the output spool is coaxially formed into a cup shaped annulus; and an input spool having a generally cylindrical shape, the input spool mounted for rotation within the second end of the outer housing shell, the innermost end of the input spool being sized to fit within the cup shaped annulus on the inward facing end of the output spool. The input spool has an axial boring at its outermost end sized to receive and be secured to a shaft powered by the automatic fuel control equipment.
