Editing Coupling (section)

===Grid===
A ''grid coupling'' is composed of two shaft hubs, a metallic grid spring, and a split cover kit. Torque is transmitted between the two coupling shaft hubs through the metallic grid spring element.

Like metallic gear and disc couplings, grid couplings have a high [[torque density]]. A benefit of grid couplings, over either gear or disc couplings, is the ability their grid coupling spring elements have to absorb and spread peak load impact energy over time. This reduces the magnitude of peak loads and offers some vibration dampening capability. A negative of the grid coupling design is that it generally is very limited in its ability to accommodate the misalignment.<ref>{{cite web|title = Why a Grid Coupling – Features & Benefits, Design Basics, and Element Options|url = http://www.couplinganswers.com/2014/12/why-grid-coupling-features-benefits.html |website=Couplinganswers.com |access-date = 2014-12-22}}</ref>
