would it be a Flyweight, by any chance?
it spins and creates the forces necessary to determine underspeed or overspeed.... like a flywheel operated torsion wrench. (instead of levering the torsion wrench on a bolt head for example, to the specified torque as in your car's engine head bolts, the torsion levering is performed by RPM... kinetic energy, with the holes used to balance the wheel itself)
at least that's what the cut away engineering drawing (plus blurb) from the earlier link, looks to be ?
