An adjustment stroke connection for a mechanical press includes an eccentric bushing disposed within a press connection member and an eccentric crankshaft member disposed within the eccentric bushing. A rotatable crankshaft is connected to the eccentric member. A mechanism is provided for connecting the eccentric bushing with the press connection member in a manner that prevents rotation therebetween and concurrently permits rotation of the eccentric member relative to the eccentric bushing. When the mechanism is activated, driving rotation of the crankshaft produces a press stroke adjustment. A torque actuator delivers equal driving torque to plural eccentric crankshaft members to enable minimization of relative bushing angle slip. Suitable control of the bushing angle and slide position crank angle during bushing expansion and contraction also minimizes relative bushing angle slip.
