1. A hydraulic line attachment device comprising: (a) a first assembly comprising a first frame, a plurality of first hydraulic line couplers, and a first coupling member;(b) a second assembly comprising a second frame, a plurality of second hydraulic line couplers, and a second coupling member;(c) the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers are constructed so that they are closed to flow of hydraulic fluid therethrough when disengaged, and open to flow of hydraulic fluid therethrough when engaged;(d) at least one of the first coupling member and the second coupling member comprises a shaft, the shaft being constructed to engage the other of the first coupling member and the second coupling member, and wherein the other of the first coupling member and the second coupling member comprises a cylinder, wherein the cylinder engages the shaft so that as a result of rotation between the shaft and the cylinder, the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers are engaged or are disengaged depending on the direction of rotation;(e) wherein engagement between the cylinder and the shaft comprises a pin engaging a spiral track; and(f) a handle coupled to one of the first coupling member or the second coupling member so that moving the handle causes engagement and disengagement of the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers. 2. A hydraulic line attachment device according to claim 1, wherein at least one of the first assembly and the second assembly is attached to a motor vehicle, and wherein the other of the first assembly and the second assembly is coupled to hydraulic lines attached to a front-end loader. 3. A hydraulic line attachment device according to claim 1, wherein each frame is constructed for holding at least four hydraulic line couplers. 4. A hydraulic line attachment device according to claim 1, wherein the handle causes the shaft to rotate within the cylinder. 5. A hydraulic line attachment device according to claim 1, wherein the plurality of first hydraulic line couplers are constructed to interlock with the plurality of second hydraulic line couplers by a ball bearing arrangement. 6. A hydraulic line attachment device according to claim 1, wherein at least one of the first assembly or the second assembly comprises a bracket for attaching to a motor vehicle. 7. A method for using a hydraulic line attachment device, the method comprising: (a) engaging a plurality of first hydraulic line couplers to a plurality of second hydraulic line couplers to provide flow of hydraulic fluid through the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers for powering at least one hydraulic cylinder, wherein: (i) a first assembly comprises a first frame, the plurality of first hydraulic line couplers, and a first coupling member, and a second assembly comprises a second frame, the plurality of second hydraulic line coupler, and a second coupling member;(ii) at least one of the first coupling member and the second coupling member comprises a shaft, and the other of the first coupling member and the second coupling member comprises a cylinder, and rotation between the shaft and the cylinder, causes the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers to move toward or away from each other depending on the direction of rotation, wherein engagement between the cylinder and the shaft comprises a pin engaging a spiral track;(iii) a handle coupled to one of the first coupling member or the second coupling member so that rotating the handle in a first direction causes engagement of the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers; and(b) disengaging the plurality of first hydraulic line couplers from the plurality of second hydraulic line couplers by rotating the handle in a direction reverse to the first direction. 8. A method according to claim 7, wherein the first direction and the direction reverse to the first direction are in a plane perpendicular to an axis of movement of the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers when moving into or out of engagement. 9. A method according to claim 8, wherein the plane crosses the axis. 10. A method according to claim 7, wherein the plurality of first hydraulic line couplers are attached to hydraulic lines containing hydraulic fluid therein, and the plurality of second hydraulic line couplers are attached to hydraulic lines containing hydraulic fluid therein. 11. A method according to claim 10, wherein the step of engaging comprises overcoming the weight of the hydraulic fluid in the hydraulic lines. 12. A method according to claim 7, wherein at least one of the first assembly and the second assembly is attached to a motor vehicle, and wherein the other of the first assembly and the second assembly is coupled to hydraulic lines attached to a front end loader. 13. A method according to claim 7, wherein the plurality of first hydraulic line couplers are constructed to interlock with the plurality of second hydraulic line couplers by a ball bearing arrangement. 14. A method according to claim 7, further comprising: (a) flowing hydraulic fluid through the plurality of first hydraulic line couplers and the plurality of second hydraulic line couplers for moving hydraulics cylinders after the step of engaging and before the step of disengaging.
