A multi-section conveyor is assembled from at least one power driven section and a plurality of non-powered sections that derive operating power from the powered section through a coupler linking the sections in tandem. The conveyor sections each have opposite end rollers with a central roller core carrying a diametric cross-pin. The coupler between each pair of sections consists of a pair of shafts linked to transmit the rotation of one shaft to the other, and each shaft is receivable within one of the roller cores. The shaft end so receivable is slotted to engage the cross-pin and thus becomes locked into rotation with the roller. One of the shafts may extend relatively further than the other for initial engagement of the coupler with one roller at a time, and the shaft diameter of one or both shafts may be reduced adjacent to the axial position of the slot where the cross-pin will be located after the coupler is fully engaged with both rollers to provide dynamic locking of the coupler to the joined conveyor sections during conveyor operation.
