An improved multibank rotary engine. The engine includes a plurality of concentrically arranged rotary engines each having a number of cylinder assemblies, pistons and cam followers arranged to impart forces and motions to and from an eccentric cam track disposed in a housing. Each of the rotary engines can be selectively coupled or uncoupled from the other engines. A device is provided for angularly indexing the output shafts of the engines with respect to each other when the engines are to be coupled together so that corresponding respective cylinder assemblies for adjacent ones of the respective engines can be angularly offset by a number of degrees equal to 360 divided by the total number of cylinder assemblies on all the engines coupled together. In a preferred form, the device is a planetary type gearset. In another preferred form, the device is a harmonic drive gearset.
