A system for transferring torque between a pair of independently, concurrently rotating shafts of a turbofan engine (10) includes a magnetic gearbox (110). The magnetic gearbox (110) has a first ring structure (116), a second ring structure (112) and an intermediate ring structure (114). Each ring structure has an annular aperture therethrough and a plurality of permanent magnets (202) embedded therein. The intermediate ring structure (114) is disposed between the first (116) and the second ring structures (112). Each ring structure is coaxially concentric with, and independently rotatable with respect to the remaining ring structures. The first (116) and second ring (112) structures are each coupled to separate ones of the rotating engine shafts, and the intermediate ring (114) is operable to transfer torque between the pair of shafts. Preferably, the intermediate ring structure (114) is coupled to a rotating machine. The rotating machine has a controller, and is operable for adjusting a ratio of torque transferred between the pair of shafts.
