A disc pack coupling for transmitting torque between two shafts approximately aligned on a shaft axis includes a first hub assembly, a second hub assembly, and a center member extending between the first and second hub assemblies. In three of the rays, a frame extends diagonally downward and outward from the core. The urethane sand core is placed in compression to increase the core strength during handling, placing inside of the mold. Based on a determination of what resources on which to generate the VM clone, the VM generator creates the VM clone on the determined resources, having the identified state.
