This disclosure describes an arrangement of axially-aligned motors and tubular or solid drive shafts enabling multiple motors and drive shafts to operate within a compact volume. The motors are axially-aligned to each other and each motor comprises a drive shaft that is axially-aligned to the motor and to the other drive shafts. At least one drive shaft is tubular thus allowing one or more drive shafts to fit within each other just as a telescoping apparatus operates. Drive shafts can thus encompass virtually the same space while rotating at the same or different speeds and directions and can have the same or different torques imparted upon them.
