The coupling device as defined in claim 2 wherein said insertion member further comprises: front and rear stop plates respectively located at opposite end portions of said insertion member, with said elongated slots being located between said stop plates; a slide block located within said receiver insertion member and being adapted to slide therein, said slide block having an aperture with a diameter smaller than the width of said elongated slots and being coextensive therewith; a first cushion member positioned between said slide block and said rear stop plate; a second cushion member positioned between said slide block and a front stop plate; said main pin passing through said slots, said receiver structure apertures and said slide block aperture to thereby attach said receiver insertion member in said receiver structure and permit limited relative movement between the same along said slots while compressing one of said cushion members depending upon the direction of movement of said receiver insertion member relative to said receiver structure. 4. The coupling device as defined in claim 3 wherein said main pin has a releasable locking means adapted to prevent removal of said main pin from said slots, said receiver structure apertures and said slide block aperture. 5. The coupling device as defined in claim 3 wherein each of said first and second cushion members is generally bullet-shaped with a hemispherical portion contacting said rear stop plate. 6. The coupling device as defined in claim 5 wherein said first and second cushion members are fabricated from a polyurethane material. 7. The coupling device as defined in claim 1 wherein said ball hitch means comprises a ball with a post attached thereto, the second end portion having an aperture therein through which said post can be inserted, said hitch means having fastening means operatively attachable to said post for securing said hitch means to said second end portion of said tongue member. 8. The coupling device as defined in claim 1 wherein said hitch assembly comprises: an elongated hollow generally square tube having a tongue aperture and a tongue lock aperture in said outer end portion; connecting means operatively positioned in said tongue aperture and being attached to said tongue member, whereby said tongue member is rotatable relative to said square tube; a tongue locking lever operatively positioned in said tongue lock aperture and adapted to releaseably engage said tongue member to lock the same at a predetermined pivotal position. 9. The coupling device as defined in claim 8 further including a first biasing means is operatively associated with said square tube and said tongue locking lever for biasing said lever toward locking engagement with said tongue member when the same is located in said predetermined pivotal position. 10. The coupling device as defined in claim 9 wherein said first biasing means comprised a compression spring located in said square tube having one end bearing against the inside wall of the top thereof, said locking lever having a transverse extension for engaging the opposite end of said compression spring. 11. The coupling device as defined in claim 8 wherein said tongue member has a generally semicircular recess in the upper surface thereof adapted to receive said tongue locking lever, said tongue member also having an aperture in said recess adapted to receive the end portion of said tongue locking lever to l
