An electromagnetic device for overspeed control of a propeller driven by an engine shaft comprises a clutch, an eddy-current coupler, and an electromagnetic brake. The clutch is disposed to mechanically decouple the propeller from the engine shaft. The eddy current coupler is disposed to electromagnetically couple the propeller to the engine shaft when the clutch mechanically decouples the propeller from the engine shaft. The electronic brake is disposed to artificially load the engine shaft when the propeller load on the engine shaft is reduced by mechanically decoupling the propeller from the engine shaft.
