Method and system to generate structured queries is described. A target torque obtaining section obtains torque that is supposed to be transmitted from a drive-side member of the clutch to a downstream mechanism in a torque transmission path as target transmission torque, the downstream mechanism including a driven-side member of the clutch. The other driving stem has the other main stem and a male joint projecting out of the center of a rectangular or cylindrical section of the main stem. Suitable organophilic clays include mica and phyllosilicates that have been surface-treated with edge or edge and surface modifying agents.
