1. A casing flange coupling assembly comprising:
- a first casing comprising a first flange, said first flange including at least one circular bolt hole;
a second casing coupled to said first casing, said second casing comprising a second flange, said second flange including at least one circular bolt hole aligned with said first flange bolt hole, wherein said second flange at least one bolt hole has a diameter larger than said first flange at least one circular bolt hole diameter;
a bushing coupled to said second flange, said bushing comprising a body portion including a cylinder portion having a circular bore configured to receive a circular bolt, said cylinder portion having an outer diameter configured to insert into and abut the second flange at least one bolt hole;
a flange portion orthogonal and integral to said cylinder portion, said flange portion configured to couple with a load bearing surface of said second flange;
a lip portion integral to said flange portion proximate said cylinder portion, wherein said lip portion redistributes a flange load; and
