The closing of the Immediately Invoked Function Expression (IIFE) in your code snippet is not correct. It should be:

})();

This is the correct format:

(function ( /* IIFE enclosed code within this function*/) {

    ...
    ...  

})();

Additionally, you are injecting services into your configuration that should not be injected. You can use services within configuration functions without explicit injection, similar to function parameters.

Here is your code snippet following a coding standard closer to John Papa's Angular Style Guide:

(function () {

    // module definition
    var AAngScript = angular.module('AAngScript', ['ngRoute']);

    // Add controller to angular app
    angular.module('AAngScript').controller('LoginController', LoginController);

    // Inject dependencies into controller
    LoginController.$inject = ['$routeParams', '$location', 'LoginFactory'];

    // Define login controller
    function LoginController($routeParams, $location, LoginFactory){

        // vm as in view-model
        var vm = this;

        vm.loginForm = {
            emailAdress: '',
            password: '',
            rememberMe: false,
            returnUrl: $routeParams.returnUrl,
            loginFailure: false
        };

        vm.login = function () {
            var result = LoginFactory($scope.loginForm.emailAdress, $scope.loginForm.password, $scope.loginForm.rememberMe);
            result.then(function (result) {
                if (result.success) {
                    if ($scope.loginForm.returnUrl !== undefined) {
                        $location.path('/productcategory');
                    } else {
                        $location.path($scope.loginForm.returnUrl);
                    }
                } else {
                    $scope.loginForm.loginFailure = true;
                }
            });
        }
    }

        };

        vm.register = function () {
            var result = RegistrationFactory($scope.registerForm.emailAdress, $scope.registerForm.password, $scope.registerForm.confirmPassword);
            result.then(function (result) {
                if (result.success) {
                    $location.path('/routeOne');
                } else {
                    $scope.registerForm.registrationFailure = true;
                }
            });
