A torque transfer device allows torque to be input at one point of the device and transferred to another point of the device, at which the power or torque is taken from the device. The device incorporates a continuous direct drive comprised of a plurality of alternating pins and links which advance each other to provide the drive. The direct drive communicates with drive sprockets, traveling through the drive sprockets to rotate the drive sprockets to transfer torque.

What is claimed is: 1. A torque transfer device, comprising: a. a first drive sprocket and a second drive sprocket, wherein each of said first drive sprocket and said second drive sprocket have a groove formed therein; b. a shedder that is disposed between said first drive sprocket and said second drive sprocket, wherein said shedder has a an upper level, a center level and a lower level, and wherein said upper level and said lower level extend beyond a middle level on opposing sides of said shedder to form a center groove in said shedder; c. a continuous loop direct drive comprising a plurality of alternating pins and links, wherein an inside edge of each of said links engages said groove of said first drive sprocket, said groove of said second sprocket and said center groove in said shedder as said continuous loop direct drive means rotates; and d. a housing that contains said first drive sprocket, said second drive sprocket said direct drive and said shedder, wherein said housing has an upper portion and a lower portion, and said lower portion has a rib that is longitudinally disposed in said lower portion of said housing, and wherein said rib contacts said lower level of said shedder. 2. A torque transfer device as described in claim 1, wherein each of said pins has a upper section, a lower section and a center section, wherein said center section is of reduced diameter from said upper section and said lower section, and each end of each of said links has an concave surface, wherein said each end of each link adjoins one of said pins and engages one of said pins at said center section thereof. 3. A torque transfer device as described in claim 2, wherein said first drive sprocket has an upper set of teeth and a lower set of teeth, and wherein said groove of said first drive sprocket is positioned between said upper set of teeth and said lower set of teeth, and wherein said upper section of each of said pins engages said upper set of teeth and said lower section of each of said pins engages said lower set of teeth as said continuous loop direct drive means rotates. 4. A torque transfer device as described in claim 2, wherein said upper section of each of said pins contacts said upper level of said shedder and contacts an interior of said housing and said lower section of each of said pins contacts said lower level of said shedder and contacts an interior of said housing as said continuous loop direct drive means rotates. 5. A torque transfer device as described in claim 1, wherein said middle level of said shedder extends beyond said upper level of said shedder and said lower level of said shedder at a first end of said shedder and at a second end of said shedder that is opposite said first end, and wherein said middle level of said shedder engages said groove of first drive sprocket at said first end of said shedder and engages said groove of said second drive sprocket at said second end of said shedder. 6. A torque transfer device as described in claim 5, wherein said first end of said center level of said shedder that engages said groove in said first drive sprocket has a concave and arcuate shape. 7. A torque transfer device as described in claim 5, wherein said first drive sprocket has an upper set of teeth and a lower set of teeth, and wherein said groove of said first drive sprocket is positioned between said upper set of teeth and said lower set of teeth, and wherein a first end of said upper level of said shedder is near said upper set of teeth and a first end of said lower level of said shedder is near said lower set of teeth of said first drive sprocket. 8. A torque transfer device as described in claim 7, wherein said first end of said center level of said shedder that engages said groove in said first drive sprocket has a concave and arcuate shape, and wherein said first end of said upper level of said shedder has a concave and arcuate shape. 9. A torque transfer device as described in claim 8, wherein said first end of said lower level of said shedder has a concave and arcuate shape. 10. A torque transfer device as described in claim 1, wherein said inside edge of each of said links has a concave shape. 11. A torque transfer device, comprising: a. a first drive sprocket and a second drive sprocket; b. a continuous loop direct drive which engages each of said first drive sprocket and said second drive sprocket, said continuous loop direct drive comprising a plurality of alternating pins and links, and wherein each of said links engages one of said pins at each end of said each of said links, and wherein said pins are not attached to said links; c. a housing that contains said first drive sprocket, said second drive sprocket and said direct drive; wherein said first drive sprocket has an upper set of teeth and a lower set of teeth, and wherein said first drive sprocket engages said plurality of links between said upper set of teeth and said lower set of teeth, and wherein said upper set of teeth engage an upper portion of each of said plurality of pins and said lower set of teeth engage a lower portion of each of said plurality of pins. 12. A torque transfer device as described in claim 11, wherein each of said plurality of pins has a first end and a second end, wherein said first end and said second end are connected by a center member which is of reduced size, and wherein each end of said plurality of links engages one of said plurality of pins at said center member. 13. A torque transfer device as described in claim 12, wherein each end of each of said plurality of links is arcuate and concave.
