What is claimed is: 1. A pipe coupling device that secures a first pipe to a second pipe, comprising: a collar having a central axis and including a fastening mechanism disposed through a cylindrical body of the collar and transverse to the central axis; and a cylindrical collet, concentrically disposed within the collar and substantially aligned with the central axis, comprising: a first collet portion configured as an upper major arc having a transverse surface angularly offset from the central axis; and a second collet portion configured as a lower minor arc having a complementary transverse surface angularly offset from the central axis that mates with the transverse surface of the first collet portion within the collar, wherein when the fastening mechanism is tightened, the first collet portion is urged to slidably translate in an angular direction along its transverse surface, and flush over the complementary transverse surface of the second collet portion until the first and second collet portions securely clamp the pipes. 2. The pipe coupling device recited in claim 1, wherein the first collet portion and the second collet portion include a stepped lap joint which allows the first pipe and second pipe to telescope relative to each other along the central axis of the collar. 3. The pipe coupling device recited in claim 1, wherein the first collet portion and the second collet portion include an abutment joint which allows the first pipe and second pipe to substantially butt up adjacent to each other. 4. The pipe coupling device recited in claim 3, wherein the abutment joint further comprises: a first angular flange disposed on an inside of the first collet portion; and a second angular flange disposed on an inside of the second collet portion, which together form a constricting portion into which fluid enters from the first pipe having a larger diameter and exits through the second pipe having a smaller diameter. 5. The pipe coupling device recited in claim 3, wherein the abutment joint further comprises: a first angular flange disposed on an inside of the first collet portion; and a second angular flange disposed on an inside of the second collet portion, which together form an expansion portion into which fluid enters from the first pipe having a smaller diameter and exits through the second pipe having a larger diameter. 6. The pipe coupling device recited in claim 1, wherein the collar is an angled collar that receives the first pipe and the second pipe. 7. The pipe coupling device recited in claim 6, wherein the angled collar includes a first collet disposed at a first end and a second collet disposed at a second end. 8. The pipe coupling device recited in claim 1, wherein the collar includes at least one extended tapered end. 9. The pipe coupling device recited in claim 1, wherein the first collet portion and the second collet portions include an abutment surface that mates with and aligns within a retaining flange disposed within the collar. 10. The pipe coupling device recited in claim 1, wherein the fastening mechanism is at least one threaded fastener disposed within the collar. 11. The pipe coupling device recited in claim 1, wherein when the fastening mechanism is tightened, the fastening mechanism imparts a point force through the collar onto the first collet portion which in turn converts the point force onto the first and second pipes into an evenly distributed circumferential radial force surrounding each of the pipes. 12. The pipe coupling device recited in claim 1, wherein before the fastening mechanism is tightened, a predetermined separation gap is defined between the transverse surface of the first collet portion and the complementary transverse surface of the second collet portion when the collet is disposed within the collar. 13. The pipe coupling device recited in claim 1, wherein the first collet portion and the second collet portion form a splined collet that receives a first splined pipe and a second splined pipe. 14. The pipe coupling device recited in claim 13, wherein: the first collet portion includes a first splined inner surface portion and a first smooth inner surface portion; and the second collet portion includes a second splined inner surface portion and a second smooth inner surface portion. 15. A method of securing a first pipe to a second pipe within a pipe coupling device, comprising: providing a cylindrical collar having a central axis; providing a fastening mechanism; disposing a cylindrical collet concentrically within the collar and substantially aligned with the central axis, the collet comprising a first collet portion configured as an upper major arc having a transverse surface angularly offset from the central axis and a second collet portion configured as a lower minor arc having a complementary transverse surface angularly offset from the central axis that mates with the transverse surface of the first collet portion within the collar; applying at least one point force through the collar onto the first collet portion with the fastening mechanism; and compressing the first collet portion with the fastening mechanism against a second collet portion along the complementary transverse surface, thereby causing the first collet portion to translate in an angular direction along its transverse surface, until the first collet portion and the second collet portion securely clamp the pipes. 16. The method of securing recited in claim 15, wherein the first collet portion translates along a downward sloped transverse surface angularly offset from the central axis disposed along the axial length of the collar, and inward along an inwardly angled surface disposed on the complementary transverse surface of the second collet portion.
