Abstract: A device that converts an existing power tool to apply a rotational force to a spring of a rollup or overhead door counterbalancing mechanism. The device has a rotatable driven gear mounted in a casting that carries a power transmitting structure. The casting and the driven gear have slots with an open end for accommodating the shaft of the counterbalancing mechanism. A removable novel coupling structure inserts into the driven gear and connects the driven gear to the winding cone of a spring so that rotation of the driven gear will apply rotational force to the spring. The casting with the driven gear is connected to the body of an existing power tool in place of the original tool head. A motor in the existing power tool body is connected to the power transmitting structure in the casting to rotate the driven gear.
