A variable power split device having radially inner and outer races, each comprising at least two axially spaced parts. A plurality of planetary members are arranged for rolling contact between the races and a planet follower carrier engages the planetary members. A first rotatable power element spindle connects with the planet follower to couple power between the planet follower carrier and a first power element. A second rotatable power element spindle connects with the inner race to couple power between the inner race and a second power element. A third rotatable power element spindle connects with the outer race to couple power between the outer race and a third power element. Means for adjusting axial separation adjust separation of the axially spaced parts of at least one of the races to vary a power split ratio between the first, second and third rotatable power element spindles.
