A rotor assembly for a rotary power device consists of two opposed rotor sections (42) which when assembled in the stator (10) are rotated by, or can rotate a drive shaft (23). Each rotor section includes through running cylinders (24) accommodating two piston heads (28) each, and a center passage for the drive shaft (23). Each rotor section defines inwardly extending support legs (46) and a rear face (48) which act to limit the travel of the rotor sections towards one another. The base of the support legs (46) includes a socket (50) which is aligned with a socket in the rear face of the opposing rotor section. A guide pin (52) and a spring (54) are disposed in the socket (50) of the support leg (46) and the guide pin (52) extends from the socket (50) into the rear face socket. The spring (54) acts to urge the rotor sections (42) away from one another so that the end walls of the rotor assembly are in contact with the end walls of the stator (10) of the rotary power device.
