Torque transfer across an air gap

In one embodiment, an aircraft includes a wing operable to fold along a wing fold gap. The wing comprises an inboard edge flap and an outboard edge flap, wherein the wing fold gap is between the inboard edge flap and the outboard edge flap. The aircraft further includes an input shaft operably coupled to the inboard edge flap, the input shaft mechanically coupled to a first magnetic torque coupler assembly at a first end of the input shaft. The wing further includes an output shaft operably coupled to the outboard edge flap, the output shaft mechanically coupled to a second magnetic torque coupler assembly at a first end of the output shaft. The first magnetic torque coupler assembly may magnetically couple to the second magnetic torque coupler assembly across the fold gap.
